The Crowsoniellidae are a monotypic family of beetles, in the suborder Archostemata. So far, only a single species, Crowsoniella relicta, has been attributed to this family. It is a minute animal (about 1.8 mm (0.071 in)) that was collected in central Italy from calcareous soil at the base of a chestnut tree. No other specimens have been found since.[1][2]
